The remote web server contains an application server that is proneto a privilege escalation flaw.

Description :

The remote web server uses a version of Zope which is older thanversion 2.3.3. In such versions, any user can visit a ZClassdeclaration and change the ZClass permission mappings for methods andother objects defined within the ZClass, possibly allowing forunauthorized access within the Zope instance.

*** OpenVAS solely relied on the version number of your server, so if *** the hotfix has already been applied, this might be a false positive
